Procedure

To a suspension of 3.8 mg of NaH (0.10 mmol) in 3 mL of DMF at 0° C. was added 32 mg of N-(4-{-[1-(2-methoxyethyl)-1H-pyrrol-2-yl]-2,2,2-trifluoro-1-hydroxyethyl}-phenyl)-N-methyl-benzenesulfonamide (Example 79, 0.068 mmol) and the reaction mixture was stirred at 0° C. for 35 min. 6 μL of iodomethane (0.089 mmol) was added and the reaction mixture allowed to warm to room temperature and stirred for 2.5 h. The reaction was quenched by the addition of a saturated aqueous solution of ammonium chloride and the aqueous layer was extracted with ethyl acetate. The combined organic layers were washed with brine, dried over MgSO4, filtered and the filtrate was concentrated. The residue was purified by chromatography (silica, hexanes:EtOAc, 9:1) to give the title compound.
